Bystanders and tourists, soldiers, cops and Secret Service agents fall by the score in a movie about the unthinkable: a terrorist ground assault on Washington. (Hollywood is providing two such "unthinkable" assaults this year, with "White House Down" due out this summer.)

This is "Die Hard in the White House," with Gerard Butler manning up as Mike Banning, the lone Secret Service agent survivor after terrorists take over the White House and seize the president and most of the cabinet.

Not without a fight, of course. This president (Aaron Eckhart) boxes. And wait'll you see the presidential head butt.

Banning is a former White House detail member, on the outs because of a life-or-death decision he made months before. When the gunship sweeps over D.C., when ordinary Asian tourists turn out to be terrorists, when innocent garbage trucks turn into tanks, Mike's the man of the moment, dashing back inside his old stomping grounds, where a mastermind (Rick Yune of "Die Another Day" and "The Man With the Iron Fists") tells the chairman of the Joint Chiefs (Robert Forster) and speaker of the House (Morgan Freeman), "I am the man in control of your White House."

Banning is the only guy who can get to the fortified presidential bunker where the hostages are. He proceeds to stab, shoot and strangle his way through legions of terrorists, quipping in his updates as he shows off his trophies, by phone, to the rest of the government, who can only ask, "Is he alive?" about Mike's latest catch.

Butler is fine in this part, which demands little more of him than an ability to change magazines like he's done it before. Many times. Mike has skills, which work against this "Die Hard." This isn't John McClane, ordinary cop in over his head. Mike Banning has "special forces" on his resume, which robs the picture of some of its suspense.

But there's pathos amid the carnage. A good cast (Melissa Leo is a feisty secretary of Defense) does what it can with a tin-eared script, making us care who lives and who dies. As an interesting side story, Mike's wife (Radha Mitchell) is a nurse who deals with the carnage of America's darkest day in an overwhelmed hospital emergency room.

Better thrillers make more of the whole shaky state of command in such calamities, wavering over terrorist demands, stringing out the suspense and playing up the clock as it ticks toward whatever nuclear doomsday awaits should our hero fail. Director Antoine Fuqua ("Shooter") is plainly dealing with a script that shortchanges all that, and he's not good enough to overcome it.

For all the bursts of blood, the gunplay and execution-style head shots that punctuate scores of deaths, it's hard to see "Olympus Has Fallen" (that's Secret Service code) as much more than another movie manifestation of a first-person shooter video game. We've become a head-shot nation, and our thrillers are the poorer for it.

Now that Ben Affleck has shaved his good-luck Oscar beard, it's safe to officially close the book on the 2012-13 awards season so we can cast a small peek at the treasures that await. What will the best picture race look like? Here are 10 candidates (release dates may change): -- Glenn Whipp,...

Since 2002 there have been arguably 50 movies about superheroes. Arguably, because genre is tricky; it's often variations on a theme, and some variations are less obvious than others. ("Star Wars," for instance, a bit of a space western, is no one's picture of the western genre.) Oh, also:...

It's comes to no surprise to residents of the commonwealth that Virginia is growing. Like many fast-growing Southern states, Virginians appear to love sprawled-out cities and suburbs, according to recent 2014 U.S. Census estimates.
